摘要
对赞比亚某电炉渣进行光谱分析、物相分析及多元素分析。结果表明,该电炉渣含铜3.5%,铜主要以金属铜和硫化铜形式产出。根据该电炉渣的矿物学特征,采用一粗两扫两精的选别流程,实验室闭路试验可获得,铜精矿品位34.01%、回收率92.57%的选别指标,达到了该电炉渣综合回收铜的目的。
By spectrum,phase and multi-element analysis,it is found that the electric furnace slag in Zambia contains 3.5%Cu,mainly existing in the form of copper and copper sulfide.According to its mineralogical characteristics,the flotation flowsheet of one roughing,two scavenging and two cleaning was adopted.Through the closed-circuit experiment the copper concentrate with the grade of 34.01% and the recovery of 92.57% could be obtained,reaching the aim of recovering copper in electric furnace slag.
